To create the template for drilling the remaining three(3) knife-edge
baffles for later assembly into the baffle rack, I used the knife-edge
baffle with the largest aperture. In the picture above, I am just
about ready to drill the last of the three (3) laser aligned 1/4"
holes that will receive the three (3) 1/4"-20 x 3' long threaded rods
for constructing the baffle rack. As you would surmise, the three (3)
drilled holes are space 120-degrees apart, and centered so that the
adjoining hardware (nuts, washers) would not be visible past the
inside or outside edges. Once the all holes have been drilled into
this one, I will use it as a stencil/ template to mark the other three
(3) for drilling. |
